Suppose, it is calculated that 'a' is 4 and 'b' is 2 for a particular estimating line with one independent Variable. If the independent variable has a value of 5, what value should be expected for the dependent variable?

For estimating maximum value of multiple correlation, which of the following conditions should be met ? I. Independent variables should correlate high with the dependent variable. II. The Independent variables should correlate low with one another. Select the correct alternative from the following :

A

Only condition I should be met

B

Only condition II should be met

C

Both conditions I and II should be met

D

Neither condition I nor II is necessary

Consider the relational schema given below, where eId of the relation dependent is a foreign key referring to empId of the relation employee. Assume that every employee has at least one associated dependent in the dependent relation. Employee (empId, empName, empAge) Dependent(depId, eId, depName, depAge) Consider the following relational algebra query: ΠempId(employee)-ΠempId (employee⋈(empId = eID)∧(empAge ≤ depAge)dependent) The above query evaluates to the set of empIds of employees whose age is greater than that of
